Sorting by Multiple ColumnsSorting by Multiple Columns

We can also sort by multiple columns. We need to specify the column names separated by commas. Let’s look at the example that retrieves three columns and sorts the results by two of them: first by population and then by capital.


Retrieve four columns using the SELECT statement, namely: continent, region, population, and capital (please retrieve these columns in this order). Then, sort the result by two of them: first by continent, then by population.

Here's a short example of the country table:

1JapanAsiaEastern Asia377829Tokyo126714000
3MexicoNorth AmericaCentral America1958201Mexico City98881000
